the antennae. Fronto-clypeal suture strong; clypeus and 
labrum with finer and sparser punctures and pubescence 
than rest of head. Last segment of maxillary palpi 
0.26 X 0.14 mm. Details of antennal segments almost 
exactly as in butleri, except that the rami are of different 
proportions. Measurements (to a total length of 1,000 
units) : 73/49, 36/36, 115/35, 85/27, 85/24, 91/23, 85/23, 
79/22, 85/27, 85/27, 182/42. Rami, from IV to x: 121, 
176, 182, 188, 182, 176, 158. Individual rami noticeably 
thickened apically, from ca. 0.02 mm. at base to ca. 0.04 
mm. at apex. These figures are similar to those of butleri 
but the shorter rami here accentuate the thickening. Seg- 
ment XI is 24 units wide at base, gradually expanding to 
the knob, 42, at 0.6 of the way from the base, then con- 
stricts and tapers gradually to the apex. Pronotum very 
similar in detail to that of butleri, except that there is a 
pair of feeble impressions on the disc just anterior to the 
slight postero-median elevations, within the basal third. 
Details of scutellum and elytra likewise almost identical 
with butleri, except for the color pattern of the elytra. 
The punctures do not appear as distinct, because of the 
paler ground color. Pronotum 0.64 X 0.64 mm. ; elytra 
2.34 mm. long, 0.94 mm. wide at humeri, ca. 1.06 mm. at 
widest. Details of underside also much as in butleri, but 
thorax pale and legs, except coxae and tarsi, mainly dark. 
First segment of posterior tarsi 0.44 mm. long, rest to- 
gether 0.30 mm.; ratio of I to rest 1.48: 1. 
Allotype female: The remarks about the comparison of 
male and female under butleri apply equally well here. 
On a specimen 3.3 mm. long the antennae are 1.37 mm. 
long, or 0.40 as long as body. The individual measure- 
ments of the segments (to a total of 1,000 units) are: 
130/56, 75/47, 112/43, 94/51, 79/54, 69/54, 75/54, 75/58, 
75/65, 75/66, 140/82. The eyes are 0.37 X 0.31 mm. and 
are separated by 0.18 mm. The first segment of the poste- 
rior tarsi is 0.41 mm. long, the rest together 0.24 mm., 
giving a ratio of the first to the rest of 1.68 : 1. 
Holotype male and allotype female: Ramsey Canyon, 
Huachuca Mts., Cochise Co., Arizona, July 12, 1955, F. G.
